Mongodb retrieve correct json from geospatial query php

Question

I'm tring to retrieve correct JSON from this code.

$query = array( 'loc' => array('$geoWithin' => array('$centerSphere' => array(array($x,$y), 35 / 6371) )));
    $cursor = $collection->find($query);

    // How many results found
    $num_docs = $cursor->count();

    if( $num_docs > 0 )
        {
          foreach($cursor as $doc['punti'])
               echo json_encode($doc);
            }
        }
    else
    {
        echo "NO LOCATION \n";
    }

if i try to validate result in http://jsonlint.com/ it shows error.

i'll post the result of query:

{
    "punti": {
        "_id": {
            "$id": "551fb585ecba12c819000032"
        },
        "nome": "Google",
        "loc": [
            -122.083983,
            37.422969
        ],
        "icona": 1,
        "istituzione_id": {
            "$id": "551fb556ecba12c819000031"
        }
    }
}{
    "punti": {
        "_id": {
            "$id": "5520fe2becba12c003000029"
        },
        "nome": "Oracle",
        "loc": [
            -122.262168,
            37.531595
        ],
        "icona": 1,
        "istituzione_id": {
            "$id": "551fb556ecba12c819000031"
        }
    }
}

the error in JSONLint is about:

Parse error on line 16:
...1"        }    }}{    "punti": {   
--------------------^
Expecting 'EOF', '}', ',', ']'

I've tried different ways, without reaching any solution.Can Someone help me ?
